I know I have a few threads open at the moment that have this info, but those threads are not centered around this issue.
About a week after installing my E+D Phase 1+ tune, I started getting misfires. With my engine being at 36k miles, I figured that it was the spark plugs, no big deal. I flashed back to stock just to be sure, and voila, I'm still getting misfires. So I checked the coils and what do I find under coil #1? What looks to be water damage, and I cannot tell if it seeped into the cylinder, but I doubt it, the thread side of the plug didn't have the same damage as the coil side. Figured I should buy new plugs ASAP just to narrow down the issues.
So since I wanted to treat myself, and I bought a bunch of stuff from Eurocompulsion, including the Brisk Silver plugs, and I put those in last night, and flashed E+D Phase 1+. I noticed a tiny increase in performance, but as soon as I put the pedal down to the floor, bang. Misfire. Cylinder #1.
I'm at work currently, and can't go check things, but I can monitor this thread to answer any questions that can lead to me fixing this issue. I've read around and figured it very well may be the coils, which if I'm going to replace 1, I might as wel do all 4, so I'll hold off since they're kinda pricey.
Also let's go on a dealer rant!
I bought my lovely Dart from a Dodge dealership near me. Fantastic buying experience, I'll say that. However, my bumper-to-bumper expired in February, after buying the car in December. All I have left is Powertrain, and that ends at 100k miles or December 2018.
To my point:
When I found that the car was misfiring, I called up the dealer and let them know the issue. The damage in the spark plug well, the misfire, everything. The tech on the phone said "Yeah bring it in, how does 8am do for you?" Told him I would see him at 8am. Fast-Forward to yesterday morning when I went to the dealer. I get there a bit early, and I see the techs bringing in a couple cars, so I figure I should go inside and see them. Speak to the same guy I spoke to on the phone, and he asks me a couple more questions. "What's wrong?", "How many miles?", and "How long has this been going on?"
After answering his questions, he says "Do you mind waiting around for 3-5 hours? One of our techs called in sick and we won't be able to get to your car for a long time"
I tell him that I have to be at work and that I can't be there all day. He says Ok and starts tacking away at his keyboard. After about a minute, he looks at me and says "Your Bumper-To-Bumper is expired, which is what spark plugs fall under, so I would have to charge you per plug and for labor." I tell him that I have new plugs on the way, and that I would install them myself. So I asked him about the coils, and he says the same thing.
Now what makes me mad about this whole thing is this next part.
He says "I'm sorry man, I see you have quite a drive to get here.[30 min] If I knew that I would have told you not to come in since my tech wasn't here."
B**CH! You knew he called in sick and you still jerked me around, trying to get me to stay for 3-5 hours just to be told that I'd have to pay you more money since something isn't covered. Very inconsiderate person, and very unprofessional.
Anyway, what do you guys think about the misfire issue? Coils? Something different? Let me know, and thank in advance for your help!
Let me just add that I have an OBD-II scanner, and verified that it is a cylinder #1 misfire. The one with that water damage in the spark plug well. I believe the code was P0301?

wasaab ... https://www.dodge-dart.org/forum/dodg...tml#post528898... he talks about why you need to replace all 4 packs at once, we are blessed to have such knowledgeable and friendly car guys here at the ORG
Anyway i'm hoping to very soon purchase the Eurocompulsion tune as well and do some testing with it. Have to wait a bit as I had to drop $1200 on new suspension Parts for my wife's Volvo, our rough CT roads have finally worn it out after 93K.
